This video is a preview of what could be part of a future osu!museum, financed by the huge amount of money received from supporter (after buying enough jets of course).
The man you see in this video is none other than Daniel Heriberht, most commonly recognized by his pseudonym "peppus".
After creating osu! alpha 0.1 the press didn't believe in his abnormal skills, so he decided to video-tape a liveplay using a typewriter and the first prototype of osu!tablet, which was 100% made out of paper.
With the arrival of WW2 he was forced to stop playing, this was the first occurrence of somebody having to quit because of the army.
He luckily managed to survive after becoming very good friends with Hitler, who decided to then join his game by the name of "Loctavus".
This video is also what we might call the oldest "choke" ever recorded, even though at the time it was referred to as "ending goof".
